Which cities had the most cicada searches over the past 10 years? Cincinnati, Omaha, Nashville, Baltimore, Washington, Chicago, Alexandria, St. Louis, Philadelphia, and Charlotte. Time for me to move to Cincinnati!

How about Australia? Cicada searches in Australia spike in December. The largest spike was in December of 2013, which was indeed a big year for cicada emergences in Australia.

The variation year after year suggests that there is a degree of periodicity to Australian cicadas. There is always a spike around December, but some years see bigger spikes than others. Just speculation (partially because the 2004 & 2005 data seems absent) but perhaps there is a 9 or 11 year proto-periocity happening.
